Secured creditor voting rights require disclosure of security and valuation, or voting may be treated as surrender of the security. A secured creditor may vote only for the balance due after deducting the assessed value of his security, provided he, unless surrendering the security, states particulars, the date and his valuation in his proof (for Tribunal winding-up) or lodges an equivalent statement with the liquidator or at the registered office before a voluntary liquidation meeting; voting for the whole debt without such valuation is deemed a surrender of the security unless the Tribunal finds the omission was inadvertent.
